                COMPUTER SCIENCES CORPORATION TO ACQUIRE DYNCORP

Acquisition Expected to Strengthen CSC's Presence in Federal Marketplace

         EL SEGUNDO, Calif., and RESTON, Va., December 13, 2002 -- Computer
Sciences Corporation (NYSE: CSC) and DynCorp today announced they have entered
into a merger agreement providing for the acquisition of DynCorp by CSC. The
transaction is valued at approximately $950 million, including the assumption of
all of DynCorp's debt, which was $273 million of principal amount on Sept. 26,
2002. Upon consummation of the merger, each DynCorp share will be converted into
$15 in cash and $43 in market value of CSC shares.

        The transaction requires approval by the holders of a majority of the
approximately 11 million outstanding DynCorp shares as of Sept. 26, 2002, and is
subject to customary conditions, including expiration of the waiting period
under the Hart-Scott-Rodino Antitrust Improvements Act.

         The terms of the acquisition have been approved unanimously by the
boards of directors of both companies. CSC expects to conclude the transaction
during the first calendar quarter of 2003, and expects the acquisition to be
accretive to earnings for fiscal 2004 excluding the impact of a special charge
related to the transaction.

         "This action furthers CSC's strategic goals of increasing shareholder
value and growing our business both organically and by acquisition," said CSC
Chairman and Chief Executive Officer Van B. Honeycutt. "With this transaction,
we are seizing an opportunity to significantly strengthen our leadership
position in the U.S. federal marketplace, augment our capabilities to support
the requirements of the new Homeland Security Department and respond to the
federal government's initiative to increase its reliance on service providers.

         "Anticipated synergies to be realized following completion of this
acquisition will further enhance the value of DynCorp's assets and provide
benefits to CSC's shareholders," Honeycutt added.

         DynCorp, with revenues of $2.3 billion for the 12 months ended Sept.
26, 2002, is among the largest employee-owned information technology and
outsourcing firms headquartered in the U.S. The company, which employs more than
23,000 technology and technical professionals at more than 550 locations
globally, focuses on the large defense, security and civil markets. Services
include systems and network integration, high-tech range operations, global
defense logistics and maintenance services and contingency support, homeland
security services, and infrastructure management of critical defense assets.

         DynCorp will become part of CSC's Federal Sector unit, which currently
has approximately 15,000 employees and is headquartered in Falls Church, Va. The
combined organizations will provide significantly greater scale to CSC's
presence in the U.S. federal marketplace. When the acquisition is completed, CSC
will derive approximately $6 billion in annual revenue from the federal
government (based upon estimated fiscal 2003 year-end revenues) and have nearly
38,000 people serving the U.S. government globally.

         "This transaction benefits our customers, employees and shareholders,"
said DynCorp President and Chief Executive Officer Paul Lombardi. "The
combination provides our customers with broader resources and an even higher
level of quality services, while enhancing and broadening professional
opportunities for our employees. Our shareholders benefit from improved
liquidity of their investment and an opportunity to diversify their retirement
holdings. We are delighted at the prospect of becoming part of the CSC team."

         In addition to providing a larger workforce and expanded federal
customer base, the acquisition broadens the service offerings CSC brings to the
federal government. The technology and services of both companies are
complementary in most markets, allowing a greater breadth of end-to-end
solutions to be delivered to both civil agencies and the Department of Defense
around the world.

         "The capabilities of our expanded Federal Sector organization will
allow CSC to provide comprehensive services and solutions at every step of our
clients' business processes," said Paul Cofoni, president of CSC's Federal
Sector unit. "Additionally, our complementary skills will allow us to address
new markets and tackle new challenges."

         He noted that the combined organization will rank CSC as a Top 10
government contractor.

         In accordance with the terms of the transaction, the exchange ratio
determining the number of CSC shares to be delivered for each Dyncorp share is
equal to $43, divided by the volume-weighted average closing price of CSC stock
for the fifteen trading days up to and including the second trading day
immediately prior to the date of the DynCorp shareholder vote. If the average
CSC share price is above $38 or below $30, a value of $38 or $30, respectively,
will be used in the exchange ratio. If this average price is below $28, CSC has
the right to increase the cash component of the merger consideration such that
the aggregate value is equal to $55.00. If CSC elects not to do so, DynCorp has
the right to terminate the transaction.

         CSC will host an investor teleconference to discuss this transaction at
8:00 a.m. EST on Friday, December 13, 2002. The dial-in number for the live
teleconference is 1-800-289-0518 (domestic) or 1-913-981-5532 (international)
and the pass code is 181968. There will be a replay beginning approximately one
hour after the conclusion of the conference call and available until 8:00 p.m.
EST on Friday, December 20, 2002. The dial-in number for the replay is
1-888-203-1112 (domestic) or 1-719-457-0820 (international) and the pass code is
181968.

other interested parties are requested to access the call via the webcast. A
